i want to grep the multilines from the logs. and am using multiline codec in my config file.. Below are the sample pattern and config file

sample logs:  
--------------------------------------  
17 Jul 2019 00:15:00,403 | INFO | Thread-186940 | net.sf.json.xml.XMLSerializer 736 | 1050 - hermes.NMX\_AlarmInfo\_GetKPI - 1.2.0 | Using default type string

Payload: [{"period\_start\_time":"2019-07-07 16:00:00","rnc":"236","site\_id":"42596","cell\_id":"42596E6","kpi\_value":"0.00000000000000000000"},{"period\_start\_time":"2019-07-07  
--------------------------------------

In the above logs, i want to grep everything except the below line.

"17 Jul 2019 00:15:00,403 | INFO | Thread-186940 | net.sf.json.xml.XMLSerializer 736 | 1050 - hermes.NMX\_AlarmInfo\_GetKPI - 1.2.0 | Using default type string"

That means i need to grep the line which is having Inbound/outbound message as starting pattern and end with payload

Can any one help on this , how to skip the first line

My config file:  
input {  
file {  
path =\> "/etc/logstash/ESB1\_Request\_Response.log"  
sincedb\_path =\> "/dev/null"  
start\_position =\> "beginning"  
codec =\> multiline {  
pattern =\> "--------------------------------------"  
negate =\> true  
what =\> "previous"  
}  
}  
}

filter {  
mutate {  
gsub =\> [  
"message", "--------------------------------------\n", "",  
"message", "---------------------------\n", "",  
"message", '\n', "**",  
"message", '\n', "**",  
"message", '-ID:',"ID:"  
]  
}
